+The exit status of an executed command is the value returned by the
+\fIwaitpid\fP system call or equivalent function.  Exit statuses
+fall between 0 and 255, though, as explained below, the shell may
+use values above 125 specially.  Exit statuses from shell builtins and
+compound commands are also limited to this range. Under certain
+circumstances, the shell will use special values to indicate specific
